For a more advanced view check out SignalScope –
- Analyze signals coming from the iPhone’s built-in or headset microphone, or from the built-in accelerometer.
- Zoom in or out on spectrum and waveform displays with two-finger expand/pinch gestures, even while the analyzer is running.
- Pan vertically or horizontally in zoomed displays with two-finger scrolling.
- Pinpoint individual sample values or frequencies with a cursor.
- Save high-resolution spectrum or waveform display images to the iPhone’s Camera Roll photo album.
Sorry, no hardware BNC connector for iPhone as of yet ;)
